From a7eb1d66c704c884584bf00548cfdf68abfe68bb Mon Sep 17 00:00:00 2001 From: Joe Hershberger Date: Mon, 8 Apr 2013 10:32:50 +0000 Subject: mtd: Make mtdparts work with pre-reloc env The env in UBI needs to look up the mtd partition as part of relocation, which happens before relocation. Make the mtdparts code capable of working on the default env to start with. The code tries to set values in the env as well, but again, the env isn't there yet, so add a check to setenv to not allow sets before the env is relocated.
